These questions have been asked numerous times, in numerous varying ways, both here on this Discourse section of the site and on Ask Ubuntu and elsewhere:
- What do I do since there was no 26.04 release?
- Does this mean I’m screwed, and can’t use MATE anymore?
- How do I upgrade if there was no 26.04 release?
- What does this mean for the future of the MATE flavor?
This post attempts to be an all-inclusive post that can answer most of these questions. If your question sounds similar to one of these four, you should be here at this post and read through it entirely first before you post your own.
Before you read on, though, you can probably answer these questions yourself and probably others that are similar by reading these pretty well written answers on Ask Ubuntu:
- What is the current state of Ubuntu Mate 26.04? - on Ask Ubuntu
- Ubuntu-Mate 24.04, help for understanding : No 26.04 LTS version will be released - on Ask Ubuntu
What do I do if there was no 26.04 release?
You carry on as usual. The fact there was no 26.04 installer ISO for Ubuntu MATE means nothing. The underlying software is still in the repositories. The next question is similar to this, but…
Does this mean I’m screwed, and can’t use MATE anymore?
ABSOLUTELY NOT! MATE as a flavor has a new development team who have stepped up in place of it’s last leader and developers, and they are working hard to fix bugs, update the software, etc. for the future!
MATE as a Desktop Environment and its corresponding packages it usually installs with are still available in the Ubuntu 26.04 repository. You could install those components on top of any existing Ubuntu 26.04 installation by running sudo apt install ubuntu-mate-desktop and then just telling the system to use the MATE environment. You can even do this from a headless install of an Ubuntu Server 26.04 instance if you don’t want to preload the standard GNOME desktop components.
How do I upgrade if there was no 26.04 release?
While there was no 26.04 release of MATE as an official installer ISO, that does NOT mean you have no upgrade paths!
The underlying software that comprises the MATE release - selected bundled software, desktop environment, etc. - are all still available in the Ubuntu repositories. That means that you can still upgrade to 26.04!
If you are currently using Ubuntu MATE 25.10:
Just simply run the following commands on the command line:
sudo apt updatesudo apt dist-upgrade -ysudo do-release-upgrade
Follow through the update prompts. You’ll be updated to the underlying Ubuntu 26.04 release and your packages should still upgrade to whatever version of the software that MATE normally would have shipped on an ISO that is in the repositories.
If you are currently using Ubuntu MATE 24.04:
You need to wait until the 24.04 → 26.04 upgrade path is opened generally. This is typically done by the overall Release Team for Ubuntu as a whole after the 26.04.1 point release. At that time, follow the 25.10 upgrade process and upgrade as you normally would.
What does this mean for the future of the MATE flavor?
How fortunate for you: there is a new team working on Ubuntu MATE who have stepped up to help take over flavor management. They haven’t formally introduced themselves yet, but I can safely say that other developers HAVE stepped up for the future of the MATE flavor, despite its prior team lead having stepped down.
(And in case you wonder how I can say this with authority, one of the things I keep an eye on with my Community Council Member and Technical Board Member hats on is the status of flavors - this has been something I’ve kept a pulse on since before the 26.04 cycle)
Ultimately, this means that they are working to cover the missed items and gaps, and may quite possibly have a 26.10 release in October of 2026, which I believe they most likely are targeting.
This also means that bugs in the MATE environment and in packages they normally would have shipped had they have a 26.04 release are still going to get attention and fixes. So, effectively, nothing has changed. The only difference is that there was no 26.04 installer image released.
TL;DR, or if you have actually read all the way here:
Rest easy, MATE is not going away, and you are not going to get screwed over simply because there was no 26.04 installation image released for MATE.
